The transpose form configuration of Finite impulse response filter (FIR) does not support for block based processing se form FIR filter architecture is optimized and implemented.The basic Data Flow Graph (DFG) of transpose form FIR filter is converted into block based DFG and retiming is inserted in the DFG for low power consumption, reduced area and minimal delay.The generalized mathematical formulation is done for the retimed block based transpose form FIR filter and it is implemented with the block size of 4 for the filter length of 16 using Verilog Hardware Description Language (HDL).Later, it is synthesized using CADENCE-RTL compiler in TSMC 45nm CMOS library and power, area and delay reports are generated.The obtained results are compared with the few existing structures.
